O uri invention relatesz to new and useful iniprovements in'bottle capremovers.

An important object of our invention is to provideY a Aremover that isadapted to. be disposed interiorl'yr of the crimped 'skirt portion ofthe bottle' cap. when the same is.: applied to.,v the bottle and thatincludes an operating arm extending exteriorly of the cap and normallylying besidev the neck of the bottle. in a handy and unobstructingposition.

"Another object o'our invention is4 to provide a Vren'iover ofthe-above-mentioned character that includes means engageable with theskirt portion of the. bottle cap to aid in,y the removal of. the samefrom the bottle that is unique in its construction to prevent' tearing.or rupturing of the cap during its removal.

Still another object ofY our invention isy the provision of a remover ofthe above-mentioned character that is` always ready for use. and thatwill dispense with Ithe necessity. of providing a separate tool toremove the capirom the bottle.

Yetl another object oi our invention is to provide a remover of theabove-mentioned character that is simple in construction, inexpensive tomanufacture and efiicientandeicacious in the performance'of its duties.

'Other objects and-A advantages of our invention, will be apparentlduring the course of'- the following. description.

The liner I'I, of oorlg; orthe like, is disposedv within the capy and in sealing relation with theopen mouth of tlriej bottle in the conventional manner.

Our device is associated with the cap.A and liner and is adapted to beapplied to the bottle;` in the same operation with the applicationof thecap thereto. Figures 4, 5 and 6 illustrate oneI form of the invention`wherein the tongue poigtion I3` terminates at one end.- in` a circularhead,i I9 of slightly lesser, diameter than the innen diameter of theskirt I6` of the cap. The base 2B, integrally connected to the other endcfg the tongue, is of substantially greater width than the tongue and isformed with forwardly. extending tabs 2| and 22 spaced laterally of thetongue;

and terminating in close proximity to the peripheral edge of the headI9, Figure 6 illustrates the blank from which this form of the inven,.tion is formed and Figure 5 illustrates the man?.

ner in vwhich the blank is fashioned into. theIv nnished device asillustrated in Figure 4.. The

sides 23 and 24. of the blank are rolled tofbring the tabs2| and 22 in.overlapping. relation lilith`V the tongue I8, and the rolledtabsarethenarcuvately bent in a direction away from thetongue to dennethe fulcrum points 25. and 26;

In operation, the enlarged` head portion I9:l is interposed betweentheinner face-ot the top wan I5A of the cap and thenner |1 andwnh, thetongue I8- extending outwardly of the. cap. between the bottle-andthevskirt I5. The lever arm 21, formed bythe rolling operationI of. the`base 20, normally lies besidev the neck of theVK bottle, as illustratedin Figure 1, and the-ful;-

crum points 25 andv 26V are disposedslightly below; WhenI it is,desired,- to.

the rim of the skirt. remove the cap from the bottle the levertarm ismoved` upwardly, in the direction of-f the. arrow in Figure2, tobringthe fulcruin*points*` 25.and. 26 into engagementwith theouter face. ofthe.Y skirt I6. The fulcrumpoints will then cooperate withthe tongue I8to bend the portion of= theskirtlclamped therebetween and to roll theAedge of the cap upwardly to disengage the same from the bottle.

In the form of the invention, as illustrateddnv Figure 7, the tongue I8is formed' with an enform of the invention,

against displacement-` The blankA IT isjashioned of the cap is sosimilar that no further explanation is thought to be necessary.

In the modification illustrated in Figure 8, the tongue I8 is notprovided with the enlarged head portion described in the first forms' ofthe invention. 'I'he tongue extends a substantial distance beyond thetabs 2l and 22 in a manner to traverse the inner face of the top portionl5 of the cap and with the distal end 3l thereof adjacent the inner faceof the skirt at a point remote from the entrance of the tongue therein.The blank illustrated in Figure 8 is fashioned into the finished capremover in the manner described in detail for the rst form of theinvention and the operation of the same for removing the cap from thebottle is yso similar that no further explanation is thought to benecessary.

In the last form of the invention, the pressed relationlbetween thetongue I8 and the cap provided by the capping machine during theapplication of the cap to the bottle is thought to provide a suiiicientfrictional engagement therebetween to prevent slippage of the tonguerelative to the cap. In the first forms of the invention, the enlargedhead portion of the tongue is provided as a safety factor in preventingsliding of the tongue relative to the cap when the fulcrum points 25 and26 are moved into engagement with the skirt and leverage applied to thelever arm 21.

It is to be understood that the form of our invention, herewith shownand described, is to be taken as a preferred example of the same, andthat various changes in the size, shape and arrangement of parts may beresorted to without departing from the spirit of our invention, or scopeof the appended claims.
